Cover Crops
What are Cover Crops?

Cover crops are used after row crops are harvested or in between harvest and re-planting to promote general soil health in agricultural lands. Soil health is important as it means less erosion, less compaction, greater nutrient cycling, increased microbial activity and improved water infiltration into the soil, improving overall water quality. Cover crops can also contribute to weed suppression and interruption of pest cycles, while attracting beneficial insects.
Another added benefit is that cover crops can reduce the use and cost of fertilizer by supplying sufficient nutrients to the soil. When the cover crop “season” is over, crops can be harvested and used as additional forage.
Cover crops are being used on farms in our region to minimize erosion, maximize nutrient uptake in the fall, improve soil heath, and increase organic matter and field trafficability. As fertilizer prices continue to increase and producers aim to reduce N loss to the environment, they are asking about the nitrogen (N) benefits of cover crops for corn silage systems.
To begin addressing these issues and with the aim of stimulating cover crop implementation on corn silage acres in New York, the Upper Susquehanna Coalition (USC) is piloting a Cover Crop Initiative with the assistance of funding from the NYS Department of Environmental Conservation.
